(see my post very early in this thread) I really wanted a Speedseal kit for my Perkins
4-108, one of the most widely used engines on older sailboats, i.e. lots of them. I emailed the company and they said that they don't have and will never have a kit for the Perkins
. It seemed like a very dismissive "no". I have not tried to contact them since then so don't know if they are still in business. They were very good before when I got one for my Ford Lehman
years ago. Very good product. I wish I could get one still.
